Avionics Support Group has obtained a new supplemental type certificate (STC) for Boeing 737s, including the -600/-700/-800/-900 series models.
Under the new STC, ASG has obtained approval to install the Rockwell Collins TPR-901 transponders on the above mentioned 737 models. According to the new STC, installers are required to determine whether the design change that occurs as a result of the installation is compatible with previously approved modifications.
